JSON is the lingua franca of exchanging data over the net and between applications written in different programming languages. In this article, we create a tiny JSON client/server app in Go.

How to generate random numbers, and the difference between math/rand and crypto/rand.

RESTful Web API’s are ubiquitous. Time for a minimalistic, five-minutes video tutorial about REST, RESTful API’s, and buidling a REST server in Go.

Regular Expressions are slow, ugly, error-prone, incomprehensible,… Or are they? Find out by learning regexp basics.

Only a well-balanced search tree can provide optimal search performance. This article adds automatic balancing to the binary search tree from the previous article.

Search trees are everywhere: In databases, in file systems, in board game algorithms,… This post explores the probably most basic form of a tree: a binary search tree.

What are generics? Why are they considered useful? Why does Go have no generics? What shall Gophers use instead?

This article examines the nature of generics, and surveys various techniques that can be used to work around the absence of this programming paradigm.

Go is a statically compiled language. The Go runtime cannot load dynamic libraries, nor does it support compiling Go on the fly. Still, there is a number of ways of creating and using plugins in Go.

Layered software architectures adhere to the Dependency Rule: Source code in a lower-level layer can make use of code in higher-level layers, but never vice versa. Control flow, however, goes in both directions. How is this possible, given that higher-level code must not know anything about the code in lower levels?

So you have built a robotic arm? Great, let’s write some Go to make it serve your five o’clock tea. Sounds simple enough. Or is it?
